Coarse feed functions
The motorized two-speed coarse feed serves to quickly
move the specimen towards and away from the knife.
When pressing the double-arrow buttons, the coarse
feed speed is 900 µm/s; the single-arrow buttons acti-
vate a 300 µm/s specimen movement speed.
The coarse feed functions are different in the section-
ing (SECT./µm) and the trimming (TRIM/ µm) mode.
Sectioning mode (SECT./µm)
Pressing the coarse feed buttons while in the
sectioning mode (SECT./µm) a continuous
specimen movement sets in and continues
while the button remains pressed. The fast
backward button has a lock-in function (i.e.
the movement continues after the button has
been released).
To activate a fast backward travel of the specimen
press the corresponding button.
Once the button has been pressed, the specimen will
travel all the way to the rear limit stop position.
To interrupt the movement, press any one of the four
coarse feed buttons.
To activate the slow backward movement, press the
corresponding button.
The movement will continue, while the button remains
pressed.
HOME (yellow) flashes while the sample is in motion
and is illuminated continuously after reaching the rear
limit.
To start a fast or slow forward specimen advance,
press the appropriate coarse feed button.
The movement will continue, while the button remains
pressed.
STOP (yellow) flashes while the sample is in motion
and is illuminated continuously after reaching the front
limit. On reaching the front limit the instrument will also
emit a beep.
